After mating, they experience rapid physical decline, which leads to losing energy. Eventually, they become easy prey. This is part of a reproductive strategy called semelparity, where an animal ...

[ 145 ] In Western cultures since the 1980s, [ 145 ] medical providers assume that experiencing a miscarriage "is a major loss for all pregnant women". [ 123 ]
Polygyny is where one male mates with several females in a breeding season (e.g., lions, deer, some primates, and many systems where there is an alpha male). [1] A common example of polyandrous mating can be found in the field cricket ( Gryllus bimaculatus ) of the insect order Orthoptera (containing crickets, grasshoppers, and groundhoppers).
Researchers at a British university say the reason some women continually have miscarriages may be from a lack of stem cells in the uterus, or womb. As many as 25 percent of pregnancies end in ...
For animals, mating strategies include random mating, disassortative mating, assortative mating, or a mating pool. In some birds, it includes behaviors such as nest-building and feeding offspring. The human practice of mating and artificially inseminating domesticated animals is part of animal husbandry.
